In order to study the high voltage wet submersible motor temperature field distribution more accurately, the 3150kW, 6kV high pressure submersible motor was calculated. The submersible motor rotor of three-dimensional temperature field of the physical model and calculating model were established under the test data as heat source. Considering the particularity of the submersible motor cooling system, rotor cooling surface adopts the method of sectioning loading coefficient of heat transfer. The finite element software was used to calculate the motor temperature field .Besides, to verify the accuracy of the method, the calculation results and the measured value were compared with the temperature field which obtained by heat transfer coefficient using the traditional method, and a new method was provided for solving temperature field heat dissipation coefficient loaded.
